"The mental space [books] occupied is being eroded by the thousand Weapons of Mass Distraction that surround us all," Hari told me last week. "It's hard to admit, but we all sense it: it is becoming almost physically harder to read books."

[Okay, I admit I didn't actually talk with Hari. The quote is from his newspaper column. But pop over to Twitter, and you can see how, in effect, he gave me permission to paraquote him at #interviewbyhari.]

Anyway, where was I? Oh, yeah, long-form reading. Hari quotes David Ulin, author of The Lost Art of Reading: Why Books Matter in a Distracted Time, who wrote that he "became aware, in an apartment full of books, that I could no longer find within myself the quiet necessary to read." Ulin wrote that he would sit down with a book, and find his mind wandering, enticing him to check his email, or Twitter, or Facebook. "What I'm struggling with," he writes, "is the encroachment of the buzz, the sense that there's something out there that merits my attention."
